Why do I keep getting a Guru Meditation error trying to use my Windows 7 VM in VirtualBox?

For some reason, I keep getting a Guru Meditation error trying to use my Windows 7 VM in VirtualBox. I have tried:

• Deleting the VM
• Remaking the VM
• Repairing VirtualBox (Although it had an error, so I tried reinstalling it completely after. It’s still broken though)

There error can be seen in these logs on PasteBin (excerpt below) as well as the attached screenshot:
